is my micro sd broken or my tabs reader?

[noobsaibot99]

I bought a samsung galaxy tab 3 wifi, paired it with a samsung 64gb micro sd. I dont know if it's just because of downloading too much file or what but every now and then the mmc gets undetected. When it gets undetected the download starts back from the beginning. Which do you think is the prob? The mmc or the tab?

Also, Restarting the tab only gets it working again

Samsung states:
microSD (up to 32 GB) External Memory Slot
